choanoflagellate
Recent studies suggest that choanoflagellates are
cousins to all animals in the same way that
chimpanzees are cousins to humans. From left, a
choanoflagellate colony, feeding cells
(coanocytes) of sponges that resemble
choanoflagellates and a choanoflagellate with its
long flagellum and collar of filaments. There can
be millions of choanoflagellates in a gallon of
sea water. (Sean Carroll, New York Times,
